The overall design of the coat is very different to that used for the Imperial officers in Star Wars. There are some good pics of the BACK of Bruce
Greenwood's costume in hi-res floating around the web - take a look. The cut of the sleeve pieces that gives the pseudo-epaulettes look is also unique -
and rather clever.

The cap for the gray "academy instructor" uniform is different than either of the BDU hats you suggest - there's also no badge. I guess it
depends how much you want to be movie-accurate and how much you'd like to have an alternative "derivative" look, like my sketches above. I'd
suggest that if you want a cap-badge, use the UFP insignia: if you look here: (new movie
icons link) you can see a version of the UFP seal on a gold background - given that all the other icons are obviously drawn from the new movie, my guess is
that this is a representation of the cap-badge from the "admirals" uniform from the academy scenes.

Hope that helps a bit!

thanks! i'm not going for a 100% accurate uniform. i'm going to modify the SW uniform so it resembles the ST XI Officers Uniform more. i'm no good
with sewing and making costumes so i have to buy something close and alter it. i'm good at making props though. i'm modifying some action figure stands
that look like the Starfleet badge and making them into actual badges. i'll post pics when they're finished. i'll also post pics with the finished
uniform.

So here it is so far. I added the rank insignia to the collars
using reflective silver iron-on tape I got from Michael's for under $5. I used one of my Starfleet insignia badges on the chest. The pants are regular
pleated pants and the boots I got from DSW on clearance for $18. I'll post pics of me in the uniform after the convention this Sunday. P.S.visit my forum at: http://trekcostumes.proboards.com/index.cgi
here's the jacket:
